Thanks Margaret. We've altered the height of "Bishop's Lodge Muriel Linton" up even further as Cree has a photo showing over six feet. If you can find any references to 'Hadley' being tall, that might confirm this identification.
Does anyone know why this is called "Montgomery's Mistake?" I have a lot of reference books but none that discusses that and as far as I am aware to this point, it was quite successful 100 years and, maybe ironically, still hanging around to some extent. Birthed even in 1940 this probably would have been culled...........but a LOT went on with roses between 1913 and 1940..............would love some more info!
I think it is still hanging around my garden, I am glad to say. There is a little bit on the sour grapes [?] in the 1992 reference (and which originally came from the 1917 American Rose Annual)
